New Einstein Owner

Hi there, just added a brand new Einstein to my collection, which is now
Bogner Shiva
VHT Pitbull 50ST
Diezel Einstein

The VHT was supposed to cater to my heavier sounds, but now that I have the Diezel, the Pitbull can go (cat beat dog so to say )

I have some Questions to you long time users:

Model Revisions:
Have there been any revisions of the Einstein or is my early series model (Ser# 003/125) identical to the current production ones?

Settings:
Are there any sample settings? How do you guys set Channel Volume vs. Master Volume vs. Presence vs. Depth for example? How many mids do you dial in? How much gain?

Parallel vs. Serial Loop:
I have lots of fun with the amp, but it seems the Parallel loop is almost not useable with my FX unit (Lexicon MX200 - too much FX level even on very low settings when I do as advised and make it 100% wet), so I'll rather use the Serial Loop.

Master / overall Volume:
Master Vol seems quite sensitive on the lower end of the spectrum, not easy to dial in those great tones at just TV-level like I can with the Shiva. Once you have it, it sounds good at lower volumes, but needs some rather sensitive adjustment to get there. Wondering whether a different pot (linear taper?) could improve the situation.

Summary:
Other than that, I like the "Eini" a lot, it is the perfect companion to the Shiva which is more on the smooth side of the spectrum, the Einstein can cover the more agressive/beastier stuff. Funny I went for another "German Design" amp
My most liked sound is actually Mode3 in Ch1 or Mode2, which can really give you that Plexi with some added razorblades feel. [/b]

Don't you mean Dog beat Dog? Einstein is Peter's dog. It's a dogo eat dog world and Einstein fought off the pitbull! There's a picture of Einstein (the dog, not the amp) on the diezel website in the pictures of the workshop. (Only the rear end though, not the face. Otherwise people might kidnap him and hold him hostage for 1 of each diezel amp and cab!)

Can't really say for the other questions as I don't have the Eini, I've got a Herbie (as you might have guessed from the avatar!).

I assume with the parallel loop you are putting your FX unit 100% wet, not the actual parallel mix level on the amp (as in none of the original sound comes out the FX unit, only delay repeats, and reverb reflections, etc. - this could otherwise be known as "kill dry" or "sidechain" and may have it's own on/off setting somewhere to stop any of the original dry signal passing). If not you'll just have the original signal (with a slight out of phase issue) mixed with another Original Signal+FX that goes higher than unity gain. Is it the input to the FX unit that is too high, or the signal coming back?

If you can't then setting the FX with normal levels in the serial shouldn't be a problem, but levels wise I'd have thought it would be the same. Dunno.

Yes, I put the Lexicon on 100%wet and then adjust the FX amount with the Parallel FX level poti, but it's already too much effect when I turn the poti at the amp from 0 to "0.0001". And if I turn down the vol. on the Lexcicon to compensate for the high amount of effect signal, I am not using its 24 bits and it sounds flat and thin.

Basically, serial loop with 10% wet on the Lexicon is fine, as it's a very neutral sounding unit, but would have been nice to use the Parallel loop and retain more of Einis pure tube circuit.

Does the Lexicon not have an analogue overall output volume knob, or digitally controlled analogue output level? Or an "output range" setting so it can drive either power amps, or different studio/consumer line levels or something? With my G-major I set the channel volume of my herbie to 12o'clock-ish. The g-maj, has a "consumer" and pro" input range, and a knob for input, so I can adjust to get the most bits & bytes used, then have an output knob, but also a setting for output range, which can be selected from about 4 choices ranging from -something to +22dBu. Dunno if the lexi manual is any help, but if it's too hot for the diezel's return I'd have thought it too hot for a lot of various other applications too!?!

Likewise I'd have thought you'd get too much return if you use the serial loop instead, and it might seem ok, but it wouldn't sound as good as if approximately unity gain. Most FX should be able to have unity gain roughly, or they'd be no good in a recording console or any kinda insert.

I prefer mine with different preamp tubes and powertubes. I currently use Svetlana/SED 12AX7 in V1 and GT 12AX7M in V2 and V3, other preamp tubes stock. Power tubes are Svetlana/SED 6L6GCs.

At home I set the master volume to about 8:00-8:30 o'clock and the channel volume at around 1:00. Preseence generally stays between 11-12 o'clock and depth at 10-12 o'clock depending on the guitar (at 12 o'clock for single coil Strat, at 10-11 o'clock for my humbucker guitars).

For gain I set the first channel in mode 2 to about 2:00 clock at most. In mode 3 I NEVER put the gain above 12:00. For the second channel the gain always stays under 11:00.

Had an interesting effect pulling 2 tubes today. Perceived difference in volume is quite significant (although maybe very little in theory). The amp became looser and sounds a bit further away, less direct than with the 4 EL34s/100W. I prefer the 100W response and sound but the lower volume of the 50W.

The bias test points are great. I will get other tubes, a good pair of 6L6s to try in combi with EL34s as well. Wondering how a pair or quad of 6V6s would do in there ...

It doesn't take 6V6 tubes as was stated in another thread.

Have there been any revisions of the Einstein or is my early series model (Ser# 003/125) identical to the current production ones?

........................... it´s brandnew

Thanks Peter, that#s great to hear.

How much is the plate voltage on the Einstein?

I was wondering whether EH6V6 could work as they advertise them safe up to 475 V
